Solved: 750W PSU recommendation

[InfernoReaper]

Does anyone have a recommendation for a 750W power supply? I've been looking around NewEgg and I've narrowed it down to two.

Silverstone ST75ZF

Silverstone ST75F

The only difference I see besides fan size is the ST75F is modular and has 4 more molex and 1 more floppy connectors.

If you have any other recommendation for a 750W PSU for under $150 (after rebates), I'll gladly take them into consideration.

Thanks in advance for the help.

If you can add a couple of buck to your budget, I would highly recommend this unit.

$159.99 including shipping

Actually it only works out to be about $12.75 more than the Silverstone ST75F
which was advertised at $136.99 + $10.25 shipping = $147.24

PC Power & Cooling 5 year limited warranty

Silverstone 3 year limited warranty

Like win2kpro said, that PC Power&Cooling 750w unit is very nice.

The thing that is very good is that its a single +12V rail w/60amps, which is the best for power distribution in your computer. All the hardware will get the power where it needs it, when it needs it.

Also to consider is the Silverstone OP750. It also has a single +12V rail w/60 amps. The Silverstone OP is also a bit shorter in size then the PC Power&Cooling, which will make it an easier fit in some cases (especially if you have a top fan on your case). The Silverstone Op750 is about 150mm long, whereas the PC Power&Cooling 750 is about 220mm long.

SilverStone OP750 $152.99:

Both units have been tested by multiple hardware sites and have been found to be extreamly good. The PC Power&Cooling 750w unit is the better power supply by a small margin ( I believe it had less ripple, but both units were well within specs) but, if size is an issue, the Silverstone OP750w unit is the way to go.

If it was me buying a 750w power supply, I would choose between those two, and those two only.

Hope this helps

By 10 miles, the PC Power & Cooling brand power supplies are the best available, bar none. They are well worth the money.

Here is another very good single rail 750 watt if you're willing to spend the money.

I've looked at PC P&C, and that particular PSU, for a while. I was under the impression an EPS PSU would not work in an ATX motherboard, so I didn't bother. Do EPS PSUs work on ATX boards?

Space isn't a problem. ThermalTake Armor Jr. case (possibly Armor later.)

Quick question: Why is everyone so intent on a single 12V rail?
I was planning on keeping the PSU until I can get a Phenom and another 8800GTS and I would have thought quad 12V rails would be a smarter move.

Because that single 12V rail is running 60Amps. Which is a lot!

Also, aren't SeaSonics on about the same level as the PCP&C?

Yes.

The second paragraph is more relevant IMO.

With all the hype about multiple 12-volt rails (ads claim that two rails is better than one, five is better than four, etc.), you'd think it was a better design. Unfortunately, it's not!

Here are the facts: A large, single 12-volt rail (without a 240VA limit) can transfer 100% of the 12-volt output from the PSU to the computer, while a multi-rail 12-volt design has distribution losses of up to 30% of the power supply's rating. Those losses occur because power literally gets "trapped" on under-utilized rails. For example, if the 12-volt rail that powers the CPU is rated for 17 amps and the CPU only uses 7A, the remaining 10A is unusable, since it is isolated from the rest of the system.

Since the maximum current from any one 12-volt rail of a multiple-rail PSU is limited to 20 amps (240VA / 12 volts = 20 amps), PCs with high-performance components that draw over 20 amps from the same rail are subject to over-current shutdowns. With power requirements for multiple processors and graphics cards continuing to grow, the multiple-rail design, with its 240VA limit per rail, is basically obsolete.

PC Power and Cooling is once again leading the industry. All of our power supplies now feature a large, single 12-volt rail. The design is favored by major processor and graphics companies, complies with EPS12V specs (the 240VA limit is not a requirement) and is approved by all major safety agencies such as UL and TUV.3

The PC P&C unit I recommended will definitely work with ATX boards. I primarily build with ATX boards and have used the PC P&C units and never had a problem.

Here is a link to a one page article that may answer some of your questions regarding power supply's.

Also, I AM NOT a fan (no pun intended) of modular power supplys. In electrical circuits every "break" in the circuit is a potential source of problems. Excess wiring in a hard wired supply does not present a problem. The chassises I use have 4 external 5.25" bays. Since I always install 2 optical drives I install the 2 drives in the 2 lower bays, and after installation I take the excess unused wiring, bundle it, cut down an old motherboard static bag, secure the bundle in the 2 unused 5.25" top bays, and have a nice, neat storage area.

If I later add a component and need a lead from the "storage" I simply open the bag, extract the lead I need, re-bundle the bag, and return it to the "storage" area.

 

[Mr.Magee]

I'm also not a fan of the modular psu's. If you were talking about the SeaSonic, not all of them are modular. (which I'm sure you probably new)

 

[Mr.Magee]

Also another thing for you to consider if noise is an issue. I've heard that the PCP&C are very loud. Never had experience, but thats just what I have read. Where as the SeaSonics are virtually silent during operation.

 

[win2kpro]

As to modular I wasn't speaking of Seasonic. One of the posters original Silverstone choices was modular, and I was just throwing out my opinion on modulars.

Seasonic is a very good manufacturer, although I haven't used a Seasonic unit, I haven't personally noticed the PC P&C as being excessively noisy.

 

[Jackiefrost9]

Seasonic is a very good manufacturer, although I haven't used a Seasonic unit, I haven't personally noticed the PC P&C as being excessively noisy.

I've used seasonic power supplies in 3 builds now (including my own computer) and I haven't had a problem yet.

Thank you (and wink2pro) for the link. It makes sense to me now.

I'm not much of a fan either of modulars. I do the same thing you do with your extra cords, except I don't put them in an anti-static bag, which is probably stupid on my part.

I'll go out and take another look and come back with a couple new ones.

 

[InfernoReaper]

SeaSonic only had up to 700W PSUs on NewEgg, which is where I'm ordering everything but my CPU cooler, so I didn't figure them in.

Here's my two new choices.

PC Power & Cooling 750W Silencer

Silverstone 800W OP800

I'm a bit iffy on the OP800 because it doesn't have any reviews yet.

Thanks for the help.

Oh and if it helps, my specs are in my computer icon next to my username. Just add a Phenom and another 8800 GTS for my final specs.
