Graphics Card Help! - Page 2

post #11 of 16
750W is not overkill if the OP has any intention of going with SLI in the future.

Haswell is right around the corner, but don't expect deep discounts on the CPU or the motherboards for a while. Estimated price for a 4770K is around $400 - and it's 10-15% faster than a 3770K you can get for $229 if you live close to a Microcenter. The 3770K (or i5-3570K if you don't need hyper threading) is still a strong choice, and the Z77 motherboards and BIOS are fully matured at this point.

This Rosewill looks nice, problem is by the time I pay for return shipping with the SuperNova it just won't be worth it. I suppose I'm stuck with the SuperNova for now at least. Is it a bad PSU?

Thanks,
Spinny

EDIT: Awesome! I'm looking forward to these new CPU's. Anyone have any suggestions on the Graphics Card?

The main problems with the EVGA SuperNova 750 is

Way over piced
Loose voltage regulation on all rails except for the 5V rail
Crossload test results
3.3V rail failed on the second Advanced Transient Response test
Noisy fan (at high speed)
Warning: Spoiler! (Click to show)
The EVGA SuperNOVA NEX750G retails for $139.99 in the US, while in the EU its price is 93.90€. Both prices don't include VAT.



Delivered full power at 45°C
Efficient
Good ripple suppression at +12V, 5V and 5VSB
Great amount of cables/connectors
Only uses Japanese caps
Excellent voltage regulation at 5V
5-year warranty (EVGA informed us that they offer a free upgrade to a 10 Year warranty on this model, after it is registered on their website)



Price

8.1 Although the middle capacity NEX750G promises a lot and belongs to the high-end SuperNOVA series, the platform it is based on doesn't provide enough room for modifications that would allow it to meet the competition eye to eye. So, although it uses nothing but Japanese caps that manage to provide very good ripple suppression on all rails, voltage regulation is far from perfect, especially if the unit's disappointing performance on crossload tests is taken into account. We completely understand that EVGA wants to keep the cost as low as possible in order to provide this unit at a fair price, but its $140 price-tag is still too high for what this PSU has to offer. Strangely enough, its EU price-tag looks good in comparison to the competition, but hardware is much more affordable in the US, and the competition in America is tough; others may not provide eight PCIe connectors, but they do offer better performance and higher efficiency.

To wind up, the NEX750G comes with some really nice features including a ton of connectors, a unique design, the exclusive use of Japanese caps, and the five-year warranty, but its performance is limited by the platform it utilizes (the same applies to the FSP Aurum PSUs), and its high price doesn't help at all in achieving a high price/performance ratio. I think that a price close to $100 would significantly boost this unit's competitiveness by definitively helping it survive in a tough category where the competition offers products based on more sophisticated platforms that, inevitably, perform better.

I have no idea why EVGA sell these under their own name the FSP models are so average that almost every other mid or high end PSU is better

The Etasis made 1200 and 1500 watts SuperNova i call outright mediocre

Do you think there would be any Radeon's that could do what I'd like, in a 0-600ish $ price range?

Ah a noisy fan! I am definitely returning it. Hopefully these Rosewill Capstones are silent wink.gif

EDIT: In your spoiler, it says it only uses Japanese caps. What does this mean?

In the Radeon family I would look at the 7970's or maybe on the low end a 7950 or perhaps even crossfired 7950's

There's three main groupings of electrolytic capacitors in terms of quality (from best to worst: Japanese, Taiwanese, and Chinese). Here's a list of capacitors brands commonly found in PSUs today::

Japanese (all about equal quality)
Nippon Chemicon
Hitachi
Panasonic/Matsu****a (sorry about the filter, it doesn't take into account Japanese names apparently)
Rubycon

Taiwanese
Teapo

Chinese (from "best" to worst)
CapXon (Corsair uses them frequently in their cheaper PSUs lines like the CX)
Su'scon
Samxon

Note that solid capacitors don't have such a strict hierarchy, as they're all pretty reliable.
