my problem is the fact that i can't get "lobster for 5€". in other sense i can't seem to find a tier 1/2 PSU that costs less than 100€...

Some weeks ago i managed to get THIS PSU for +-40€ on Amazon.de, but problem is, it's out of stock!! It's ordered, but it will only come if stock is available. And I'm guessing that if they haven't replenished it for some weeks, it won't come back, so i need to get another model/brand.


TL;DR: managed to find excelent PSU for very cheap price. It's out of stock. All other PSUs are crap or are very expensive....

Any way you guys can put me in the right direction for a good "bang for buck" PSU?

My rig:
-Gigabyte Z97-X gaming 3
-i5-4690K
-Gigabyte GTX 970 G1
-8 GB 1600MHz


EDIT: I'm in Portugal (Europe).

well damn, that was a great shot!! oO

i'm gona assume that power and those PSUs are enough for an OC, and a possible SLI in the future? (just to be sure :) )

in any case, many thanks my friend!
 
SLI? No. You need 700-750 watts for 2 x GTX 970s. Those are all very good units but I recommend the XFX as the other 2 are older designs not compatible with Haswell's low power C states.
 
ok then, what about the hell with the SLI, and just the system i put up there, but doing OC? is the XFX PRO 550 good enough?

I know it's reliable and a very good PSU according to this list and other reviews, but is it enough if we take the SLI out of the picture?
 
Personally I think you are fine with overclocking and the XFX 550w unit as you have an Intel based system and a single GTX 970. Even RealHardTechX only recommends a 500w unit for a system with a GTX 970 and they overstate a bit for people with lesser quality units.

You could really run a GTX 970 with a good 400w-450w unit and be fine. 550 watts leaves you plenty of headroom.
 
True, but the 4690k goes from 100w at stock settings under load, to 180w at 4.5Ghz under load, and if the GPU is going to be overclocked as well, you're likely to be running fairly close to the upper 80% of capacity on that unit which means a lot of stress, heat and most probably a lot louder PSU due to it's fan running fairly high speed anytime it's under a gaming load. I'm sure it's enough capacity, I'm just not sure there's enough headroom there for optimal performance and longevity as well as running with a reasonable level of fan noise. As Anort3 indicated, it's probably ok, but it's something to think about.

But it's a very good unit so I guess I could be wrong.
 
I'm currently using an XFX TS650 80+ Bronze, but it is just too loud so I decided to upgrade to a different brand and can't decide which.

I'm stuck between two PSUs, EVGA 750G2 80+ Gold Certified or PC Power & Cooling Silencer Mk III 750W 80+ Gold Certified.

Computer specs if necessary:
CPU: Intel Core i7-5820K 3.3GHz 6-Core Processor
CPU Cooler: Phanteks PH-TC12DX_BK 68.5 CFM CPU Cooler
Motherboard: MSI X99S SLI Plus ATX LGA2011-3 Motherboard
Memory: Mushkin Blackline 16GB (4 x 4GB) DDR4-2800 Memory
Storage: Samsung 850 EVO 250 GB Solid State Drive
Storage: Western Digital Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive
Video Card: MSI GeForce GTX 970 4GB Twin Frozr V Video Card
Case: NZXT Phantom 530 (White) ATX Full Tower Case
Power Supply: XFX 650W 80+ Bronze Certified ATX Power Supply
Operating System: Microsoft Windows 8.1 OEM (64-bit)

Thanks!
 


The PC Power & Cooling Silencer MK III 750 W is based on Super Flower's Golden Green Platform.

The EVGA SuperNOVA G2 750W is based on Super Flower's Leadex Gold Platform.

Practically the same? No. The Leadex platform has proven its superiority.
 
Is the G2 as silent?

The PC Power & Cooling Silencer MK III 750W would be $160, while the EVGA G2 is $110, what would be a power supply closer to $160, and completely silent?
 
All the Seasonic X and Platinum series units and the units based on their platforms have a hybrid fan mode. I can't ever hear my Platinum 660w.

The Silencer series is only a name. They aren't known for being quiet units.
 


At 50% power draw (i.e. 375W) the G2 is half as loud as the PCP&C Silencer MK III.
 
The XFX XTR Series should be marked as a Tier Two. It is a power supply, but it is not based on the KM3 platform as was previously suggested. The 3 models from the XTR line are based on the Seasonic G Series platform, but modified to be fully modular and with a "hybrid fan-mode". It should not be in the same league as the Supernova G2. Again, its a fine power supply, but if the G series is considered to be Tier Two then the XTR should be in the same category.

It shares a model number with the XFX Pro Black Edition, which is based on the KM3 platform. However, XFX decided to reinvent the line by downgrading the platform and modifying it.

Also, the GS series is based on a Seasonic platform that offers performance that should be considered tier two. It is outclassed by the G2 series, which is based on the Superflower Leadex platform, which has proven to be competitive with top-end Seasonic platforms.

Where does the Seasonic X-Series go on this list:

Because for some reason it isn't on there.
