First of all, this is my first post so hello to everyone, and thank you all for all the discussion about computers which in last few days helped me a lot. Also, I'm sorry if my english is bad :)

As the title says, a have a question about Cooler Master B2 Series 600W power supply. I recently bought it (10 days ago), tested it and it's working fine on an very old machine, it is very quiet and after 7 hours of RAM and CPU running at 100%, it's not too hot (sorry, I didn't measure temperature) and I was pleasantly surprised. Ofcourse, I felt joy of well invested 9000 (serb) Dinars, or 81.78 USD and was all happy until I realized today that it might not be enough for my future PC build. Also, looking for answers online, I found out that a lot people think that CM's PSUs are garbage, a lot of people at Tom's too. After viewing some tips and some discussions I found out that I don't know about computers as much as I tought, so my question is:

Did I miscaculated and is it really as bad as people say and will it be enough for my future build? Also, if answers are as bad as I think, are there any better PSU within same price, I dont mind returning it to the shop and spending 10 or 20 USD more ?!

Below are "my" specs:

CPU: Intel® Core™ i5-6500 Processor;
GPU: GEFORCE® GTX 970 GAMING 4G;
RAM: KINGSTON HyperX Savage Black 16GB kit (2x8GB) DDR4 2400MHz CL12;
Motherboard: ASUS Z170 Pro Gaming.

Please, if I forgot to mention anything important, tell me.
Any help is appreciated, thanks in advance.

Thank you very much, AngelOfDarkness, I will mark your answer as solved. I guess in the future I should find more information before rushing to the shop.

Yeah you should look for reviews of everything you are looking to buy, if it doesn't have reviews it's probably not good enough.

The SEASONIC M12II Evo Edition 520W isn't compatible with the sleep states , but if you have issues it can be disabled in the BIOS.

Same goes for Skylake in terms of sleep states.

When an Intel Core (i3, i5, i7) processor is idle, it goes into a sleep state that requires less power than when the CPU is active. Since the motherboard voltage regulation modules that provide power to the CPU gets their power from the power supply's +12V rail, these sleep states can dramatically reduce the load on the power supply's +12V rail.

According to Intel's presentation at IDF, the new Haswell processors enter a sleep state called C7 that can drop processor power usage as low as 0.05A. Even if the sleeping CPU is the only load on the +12V rail, most power supplies can handle a load this low. The potential problem comes up when there is still a substantial load on the power supply's non-primary rails (the +3.3V and +5V). If the load on these non-primary rails are above a certain threshold (which varies by PSU), the +12V can go out of spec (voltages greater than +12.6V). If the +12V is out of spec when the motherboard comes out of the sleep state, the PSU's protection may prevent the PSU from running and will cause the power supply to "latch off". This will require the user to cycle the power on their power supply using the power switch on the back of the unit.

While we are still working with Intel on the details of the testing methodology they use to check PSUs for Haswell compatibility, it is already known that a power supply that uses DC to DC for the non-primary rails (the +3.3V and +5V) will not have an issue with the new low power sleep states. This is because a DC to DC buck converter is used to convert +12V to +3.3V and +5V. This means that no matter what load the CPU puts on the power supply, there will always be a load on the +12V because the +12V is required to provide power to +3.3V and +5V.

Corsair utilizes this DC to DC technology in most of their power supplies. Starting with the CX750 and CX750M and moving all of the way through the GS Series, TX and TX-M Series, the HX Series, both the AX Series Gold and AX Series Platinum, and the new AXi Series. So whatever your budget, if you choose Intel's new Haswell processor and wish to utilize the new, low power C7 sleep state, Corsair has a power supply for you

My knowledge of the how PSU works is very minimum, but if I understood what I read, this particular PSU is not compatible with CPU's sleep state which turns on only when it's idle? Please, correct me I am wrong. Good thing I can disable it, I don't want to risk damaging PSU or anything else. Also, I'm one of those guys who turn off computer before going to sleep, so if there's such a thing as CPU sleep state, I guess it's not essential for me, since PC won't work 24/7.

It looks like I'm more misinformed than I thought I was....
