Is this Power Supply Good for OC'ing?

[pcenthusiast13]

Is the Corsair CX750M good enough to over-clock a i5-4670k to around 4.2 to 4.5ghz? I heard that you need a really good one, is this good enough?

Its OK but not really good. If you need 750W try something from Tier One - http://www.tomshardware.com/answers/id-1804779/power-supply-unit-tier-list.html#13224310 eg Antec HCG 900M, Corsair AX 760, etc

I usually say no way to CX, but since it's a 750W, I'll just give you the caution signal. CX is Corsairs budget brand. They put a sticker on cheap Channel Well units, and hope that buyers won't realize there is not Seasonic under the hood.

CX is not a PSU I would put in a gaming build. It's a good PSU "for the money" .... which means it's a budget PSU and belongs in a machine with components of matching quality.

And you'll need a very very good cooler to get to 4.5 Ghz and a bit of luck.

The new CX600M surely isn't a top performer, but making it one was not Corsair's initial purpose. They were, instead, looking to offer the best possible price/performance ratio, so some compromises had to be made. Although the maximum temperature at which the unit can deliver its full continuous power is restricted to only 30°C, all of my test sessions went smoothly at a considerably higher ambient, but the CapXon caps on the secondary side most likely won't keep their good performance if they work at above 40°C constantly, which I suspect to be the reason behind Corsair's conservative temperature range, at least for full continuous power output. The strongest advantage of the CX600M is, without any doubt, that it is affordable given its performance and the modular cabling design it utilizes. Its biggest drawbacks, on the other hand, are that it only has two PCIe connectors, which greatly restricts the unit's usability, and its very low hold-up time, which is the result of the small bulk capacitor. Corsair apparently preferred using a Japanese capacitor with a smaller capacity in the APFC instead of a higher capacity Taiwanese one. They may be right, since Japanese caps tend to last much longer, but a hold-up time below 10 ms with a limit of 16 ms as specified by the ATX spec doesn't look good at all.

What about the Thortech Thunderbolt 650W 80+ Gold Certified Fully-Modular ATX Power Supply?

It's not bad at all.

I have seen several Thunderbolts reviewed but not that particular model. And it;'s big mistake to assume that two PSUs from the same series are equally good. For example:

Corsair HX850 is one of the top 3 850 watters ever made.
http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story5&reid=153
http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story5&reid=299

Corsair HX1050 is a dog w/ a 7 build quality rating
http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story5&reid=245

Best = Corsair HX650/750/850, Seasonic X Series
Next = Corsair TX V2, XFX Core Edition, Seasonic M12, Some Corsair RM, Most ANtec HCP/HCG

True. But check out the pictures in the disassembly. It looks awesome like nothing I've ever seen.

But at any rate, even jonnyguru said this is an unknown, probably pass on this one.

I would like at least a 600watt PSU with good efficiency and around $130. I would like a Tier 2 (or one) PSU, if the one I chose isnt very good.

made by Sirtec. Only the 800W is OK per - http://www.tomshardware.com/answers/id-1804779/power-supply-unit-tier-list.html#13224310

So try an Antec HCG 620M, XFX or Seasonic

 

[pcenthusiast13]

How about XFX P1-750B-BEFX or SeaSonic SSR-750RM? Do you know any other PSU's that are really good and have really good efficiency and is really good for a cheap good decent price?

 

[unknownofprob]

SeaSonic SSR-750RM <- Great choice, defiantly recommend it.
