i stick to normal PSU's only because of following reasons

• easy to get in EU
• long warranty periods (For EVGA and Corsair)
• easy warranty (RMA) handling due to EU regulations for sellers

all of my PSUs are Corsair and EVGA. Never had any problems with them. Using single rail PSU's ONLY.
Though, stay away from Enermax. Very bad support. and don't buy those second hand. only 1st buyer gets the warranty.

Not buying server PSUs due to high price connected to import tax and long shipping from USA or China.
