[SHAKING FIST]Next time Maxwell, next time!!![/SHAKING FIST]
PM me your address so I can send you your Dollar.
Hehe... Stop. Hammer time.Quote:

M'kay...last night i made a purchase to upgrade the cooling system of the Maxwell Spanker. Waiting on the parts to arrive :D I also grabbed one of those 450W drive bay PSUs i posted about. It has shown up but i can't install it until my new cooling parts arrive because of the way i have the innards of the case laid out.
Upgrading my radiator from a 2x120 to a 3x120. I'll still have the 2x120 which i can mount externally should the need arise in the future. Swiftech FTW!
Designing the system to operate without a resivoir. Purchased a fill cap. With some slight modding of the HAF X case, i can fill my coolant lines from the top of the computer case. Spiffy.
Purchased all new tubing. The interior of the tubes are coated with silver to prevent the growth of algae. Sure it was $4/foot, but cheaper than buying biocides in the long run.
I would like to thank FrozenCPU.com for supplying me yet again and helping to fulfill my dreams of crushing Maxwell :D

Since it has 2 rails I wanted to make sure I would hook it up right. Found this review while looking on the web. http://www.hardocp.com/article/2011/...supply_review/
I'm glad I only paid $20 for it. It should be OK for a card with a low power consumption. I don't think I'll be putting one of my better cards on it and no OC'ing. That's for sure.

Now to the bone. The issue I have with that review is that it is unrealistic in regards to real world application. It is primarily an auxiliary or supplemental GPU power supply. In this respect it is designed to power 2 mid-range GPUs like an ATI HD 4850 or a Single high end GPU like an ATI hd 5970.
So, 2 4850s will each draw 75W max as per the ATX specification for a 6-pin PCIe connector for a total of 150W. The ATX spec for an 8-pin PCIe connector is 150W max. The 5970 uses x1 6-pin + x1 8-pin connector. Thus the total amount of power that the card will draw from both PCIe connectors is......... 225W. This is exactly 50% of the ePower's "rated" output.
My conclusion is that this ePower PSU was never intended to actually run anywhere near 80% of rated, much less 100%. And if you review their data for all #2 tests (50% load tests) will see this is where the ePower unit performed best.
In fairness to [H]ardOCP, all other aspects of their review were spot on.
I may at some point in the future try and find a used unit and just rebuild it with quality parts, mainly the caps. I think the inductors and transformer should be fine.
F$, The 5970's are rated at 42w idle and 294w under load at stock clocks. I OC my cards pretty high and they are pulling closer to 400+w. I understand some of that power is comimg from the PCIe slot. However I don't think I trust this PSU to run my (not cheap) 5970.
Oh I wouldn't blame you for not trusting it. If you are good with a soldering iron, ten bucks in caps would make that unit a decent auxiliary PSU. As is it can handle running system fans and such without issue.Quote:

By the way thats why the 5970 are sold down clocked to 725, to keep them under that 300w threshold. I wouldn't use this psu to power 2 mid range cards either. The 5770 draws 188w under load. Two of them would push this psu into its danger zone. All in all I like the looks and the cables seem to be good but it should not be sold as 450w psu. Max I would rate it as is 225w. I really wouldn't want to push it much beyond that.
So anybody considering buying this psu be forewarned
Actually, to test a PSU at 80% load isn't exactly fair, since no PSU, regardless of brand or type, should ever be used above 75% capacity. 50% is usually the sweet spot for efficiency on any PSU, not just this one. Also, it would have no problem powering 2 mid-range GPUs. For 2 GPUs, 150W of the total comes from the PCIe slot (75W per slot) itself, which is a large chunk of the burden this drive bay PSU doesn't have to deal with. It'd do just fine.
I hope you don't mind if I join the discussion here and add my soon to be built rig. If it's a problem I'll move it to it's own thread later. :)
